Abstract

Heart disease can attack anyone at anytime. Sometimes it’s appearance cannot be dettected early. Heart examination processesthat are done by doctorscommonly called as auscultation. The auscultation is a  performance examination organs like heart by listening voice resulted from vibration of stetoscope. Furthermore, phisical examination using the stetoscope are mostly required the patients to open their chest area. For that reason, it is necessary to built a tool that is able to seperate the doctor dan the patients.        In this study, a heart sound signal auscultation through wireless transmision in the wireless sensor network is built. Quality of service that are employed in this study including probality of loss, the amount of delay of the received dataas well as the amount of heart auscultation signal bandwidth that are transmited between two nodes.Based on the result, it shows that the higher the baudrate of data delivery set by the serial communication, the larger the throughput of the system. However, it directly affects the packet loss in a way that the packet loss becomes larger. On the other hand, in terms of delay our study shows that large baudrate produces large delay data transmission. Keywords : Sinyal Auskultasi Jantung, Wireless Sensor Network, Zigbee

Abstract

Technology today has reached its advancements even in military field. Technology in this field is often utilised to make tasks easier, to overcome human errors, as well as to do high-risk tasks that seem to be impossible to be done by human beings. High tech equipments are highly required to support offense and defense of the nation as well as to diminish human losses. One of the most prominent equipments in military field is combat vehicle. Thus, combat vehicles that can adapt quickly to any unknown environments are necessary and should there be obstacles, they could evade and find alternative routes to reach a designed target.Before such technology is created, a simulation using a robot is administered. In this simulation, the robot’s movements are observed. The observation includes how the robot evades obstacles especially moving obstacles and reaches the target successfully. There has been a prior research using Fuzzy Logic Control to control the robot’s speed and determine the evading direction when it encounters obstacles. Nevertheless, that research was only tested to evade unmoving obstacles. In this research, there would be comparative analysis between Fussy Logic Control and Virtual Force Field (VFF) method to evade moving targets as well as the ability to reach the designed targets.  There are two parameters used and analyzed in this research. They are the distance between the robot and the target and time required for the robot to reach the target. Those two parameters would be calculated using Fuzzy Logic Control and Virtual Force Field (VFF) method and the result would be compared to see which one is more effective to be used in this simulation.Keywords : Simulation Robot, Fuzzy Logic, Virtual Force Field, VFF, Dynamic Obstacle Avoidance

Abstract

Pengembangan listrik tenaga surya yang berbasis pada photovoltaic dari piranti solar cell sebagai salah satu sumber tenaga listrik alternatif yang ramah lingkungan dan ketersediaannya yang melimpah. Namun tegangan yang dikeluarkan dari solar cell masih bersifat fluktuatif (selalu berubah) sesuai dengan perubahan intensitas cahaya yang jatuh pada permukaan sel surya.Pada penelitian ini pancaran sinar matahari masuk menuju ke panel surya dan sensor LDR. Hasil keluaran tegangan akan dirgunakan sebagai input pengisian catu daya baterai berupa tegangan DC. Sensor LDR mendapatkan input dari pancaran sinar matahari dan hasil pembacaan nilai sensor akan dibaca oleh ADC serta diolah oleh mikrokontroler dengan cara memetakan perubahan posisi panel surya terhadap matahari. Dari hasil pemetaan, panel surya akan digerakkan oleh motor DC untuk menuju posisi yang dapat menghasilkan sinar matahari paling maksimal.Dalam menentukan sudut sun tracking terhadap sinar matahari dapat menggunakan minimum sistem, rangkaian sensor LDR, dan modul driver motor yang dihubungkan pada panel surya sehingga panel surya dapat mengikuti arah matahari dan menghasilkan nilai keluaran daya yang lebih maksimal, karena hasil keluaran daya yang didapatkan oleh panel surya saat menggunakan sun tracking mengalami kenaikan sebesar 1,73298 watt atau setara dengan 36.833%.

Abstract

The use of graphs to analyze heart sound signals quite difficult, because the cardiac signals are retrieved and displayed into a graph requires special skills to be able to read and analyze the cardiac signal. Therefore, the authors took the initiative to create an application that can transform the heart sound signal from the time domain into the frequency domain for analysis needs.The process of transformation of heart sound signals using Fast Fourier Transform (FFT).Based on the test results showed the transformation of the heart signal from the time domain to the frequency domain in the experiment with six different cases is particularly evident in the Peak or peak frequency and maximum frequency. Abnormalities of the heart sound signal with voice disorders at low frequencies produces a frequency domain representation of the graph with a small hill in the low frequencies.
